Although we all love to press buttons, especially if they’re those extra-clicky buttons that kick your finger back as they activate, sometimes projects call for more discrete methods of user interaction, allowing users to enjoy your project like magic, with the controls hidden away and simple gestures or carefully placed knocks activating various effects. This is when you need awesome discrete Buttons & Switches such as Thin Film Pressure Sensors like these, which are little 18mm Circles that can identify and measure force between 20g and 6kg. They are made in a similar way to how many Rain or Liquid Sensors are made, measuring the resistance between elements as the conductivity fluctuates, although instead of using liquids as the conducting element, the flexible PCB stretches, pushing the elements closer together or further apart, resulting in a change in resistance and being identified as pressure.

In a similar fashion to the smaller 8mm OD Pressure Sensors that we stock, these 18mm OD sensors are a great choice for both discrete and standard applications, offering a tiny form factor that can easily be hidden away behind a collar or cuff, or simply installed in plain view for all to see. This open-ended nature is then complemented with both static and dynamic load capabilities, meaning that it can be used as both a standard button, but also as a sort of Load Cell or weight sensor, keeping track of the contents of snack jars or activating your personal fan when you sit down. However you want to use them though, you can enjoy the ultra-simple 2-wire interfacing, discrete form factor, as well as versatile style of usage for an incredibly wide range of projects and applications.

Finally, if you can see a lot of potential in these tiny, handy sensors, but are looking for versions with different shapes, sizes or tolerances, don’t forget to check out the entire Thin Film Pressure Sensor Range that we have to offer.
